I. Habitat loss and habitat fragmentation
A. As habitat is lost, what remains is
typically separated into small patches that are isolated from one
another
B. Spatially divided habitats are not
caused only by humans, but can occur naturally in many situations

C. Important aspects of fragmentation
1. Local
extinction refers to population loss within a fragment
2. Fragment area
– larger fragments tend to have larger populations
3. Fragment
isolation – nearby Fragments have higher population sizes

D. Consequences of habitat fragmentation
-- small populations

II. Conservation in fragmented landscapes
1. Corridors are thin strips of habitat
that connect otherwise isolated areas and ideally increase
population sizes and reduce local extinction
